Chikoka cha siteshoni ya asphalt yosakaniza sichikhoza kuchepetsedwa. Zimakhudzanso kwambiri kutentha kwa chitoliro chotumizira phula. Izi zili choncho chifukwa zizindikiro zofunika za phula, monga viscosity ndi sulfure, zimagwirizana kwambiri ndi malo osakaniza phula. Nthawi zambiri, kukhuthala kwakukulu, kumapangitsa kuti atomization iwonongeke, yomwe imakhudza mwachindunji ntchito yabwino komanso kugwiritsa ntchito mafuta. Pamene kutentha kumawonjezeka, kukhuthala kwa mafuta olemera kumachepa pang'onopang'ono, kotero kuti mafuta akuthamanga kwambiri ayenera kutenthedwa kuti ayende bwino komanso atomization.

Choncho, kuwonjezera kumvetsa zizindikiro zake ochiritsira posankha, muyenera kudziwa ake mamasukidwe akayendedwe-kutentha pamapindikira kuonetsetsa kuti Kutentha kungachititse phula kufika mamasukidwe akayendedwe chofunika ndi burner pamaso atomization. Poyang'ana kayendedwe ka asphalt, anapeza kuti phula mu payipi yolimba chifukwa kutentha kwa phala la phula silinakwaniritse zofunikira.
Kupenda zifukwa, zifukwa zazikulu ndi izi:
1. Tanki yamafuta apamwamba amafuta otengera kutentha ndi otsika kwambiri, zomwe zimapangitsa kuti mafuta asayende bwino;
2. Chubu chamkati cha chubu chamagulu awiri ndi eccentric;
3. Paipi yamafuta otengera kutentha ndi yayitali kwambiri;
4. Paipi yamafuta otengera kutentha sikusamalidwa bwino. Miyezo yoyenera yotsekemera, ndi zina zotero, izi ndizinthu zazikulu zomwe zimakhudza kutentha kwa kutentha.
